Polypropylene staple fiber, scientifically known as polypropylene fiber, is a fiber made of propylene as a material through polymerization and melt spinning. The following is a detailed introduction to the production process of polypropylene staple fiber!

The principle of the Polypropylene staple fiber process is to use the properties of polyaddition reaction to form a polymer through propylene polymerization, and then stretch and cut the fiber into shape.

The specific steps include: gasifying propylene, then cooling and vaporizing; polymerizing the obtained propylene to obtain polypropylene particles; granulating the obtained polypropylene particles to obtain polypropylene staple fiber.

Application areas of Polypropylene staple fiber:

Textile field: Polypropylene staple fiber can be mixed with other fibers to make socks, jackets and sportswear. Because it is non-hygroscopic and easy to clean, it is also commonly used to make waterproof fabrics and geotextiles.

Automobile manufacturing: In the automobile manufacturing industry, Polypropylene staple fiber is used as a reinforcing material to improve the strength and durability of automobile parts.

Building materials: In the field of building materials, polypropylene staple fiber is often used to make concrete reinforcement mesh and waterproof materials to improve the durability and waterproof performance of buildings.

Other fields: Polypropylene staple fiber is also widely used in carpets, decorative fabrics, ropes, industrial filter press cloths, packaging materials, civil construction cloths, fishing net cloths, water hoses and other fields. In addition, gauze made of polypropylene does not stick to wounds, and often replaces cotton gauze for medicine application and is used as a sanitary product. The flocs made of polypropylene hollow fiber are light, warm and elastic, and the new ultra-fine polypropylene fiber is an excellent wear-resistant material.

Lightweight: Polypropylene staple fiber is the lighter fiber among common chemical fibers.

Corrosion resistance: Polypropylene staple fiber has good corrosion resistance.

Antibacterial and anti-odor: Polypropylene staple fiber has strong anti-fouling and anti-odor capabilities, and can be antibacterial, anti-mildew and antibacterial.

Hubei Botao Synthetic Fiber Co., Ltd. was founded in October 2000 and is located in Jingmen City, Hubei Province. It specializes in the production and sales of polypropylene, polyester, composite fibers, and polylactic acid staple fibers. Its products are mainly used in non-woven fabrics, automotive interiors, geotextiles, carpets, filtration and other industries. As the company continues to expand, it has established three subsidiaries at home and abroad, namely Jiangsu Botao New Materials Co., Ltd., Hubei Green Ring Chemical Fiber Co., Ltd. and Tianlong (Thailand) Co., Ltd., with a total area of 300,000 square meters. The company has introduced a number of imported fiber production lines, with fixed assets exceeding 300 million yuan, an annual output of 100,000 tons of polypropylene staple fibers, 20,000 tons of polyester staple fibers, and 10,000 tons of composite fibers, with an annual output value of over 800 million yuan. Focusing on the field of synthetic fibers for more than 20 years, Botao Synthetic Fiber has achieved excellent market results and extensive honors with the mentality of striving for excellence and honest development. In 2014, as the vice president unit of the Polypropylene Branch of the China Chemical Fiber Association, it participated in the drafting and formulation of the "Polypropylene Staple Fiber" industry standard; in 2018, it won the title of "Invisible Champion Technology Little Giant" in the subdivision of the pillar industry in Hubei Province, and is a provincial-level specialized and new little giant enterprise...
